Repair

• Replace or repair leaky seals or fittings using appropriate techniques.
• Clean or remove obstructions that are causing flow rate issues.
• Calibrate or replace electrical components that are faulty.
• Adjust regulators or gauges to ensure proper operation.

8. What is the importance of preventive maintenance in air value systems?

• Regular inspections and maintenance help detect and address minor issues before they become significant problems.
• Reduces the risk of unplanned system failures and costly repairs.
• Ensures the system operates safely and efficiently, providing optimal comfort and air quality for passengers.

9. How do you stay updated on advancements in air value testing technology and procedures?

• Attend industry conferences, workshops, and training programs.
• Read technical publications and research papers related to air value testing.
• Consult with experts and colleagues in the field to exchange knowledge and best practices.

10. Describe a challenging air value testing experience you encountered and how you resolved it.

In a recent incident, a passenger reported feeling faint during a flight due to a suspected air conditioning issue. I was tasked with testing and troubleshooting the system.

• I conducted a thorough inspection and discovered a small leak in one of the air conditioning ducts.
• Using specialized leak detection equipment, I pinpointed the exact location and repaired the leak using a sealant and patch.
• Subsequent testing confirmed that the system was functioning properly and providing adequate airflow throughout the cabin.
